IMPROVEMENT IN MEANS OF OPERATING SHIPS PUMPS.

Specification formingpart of Letters Patent N0. 135,094, dated January 2l, 1873.

To all whom it may concern.'

Be it known that I, SPENCER RUDING DEVERELL, of Mount Gambier, in the British Colony of South Australia, telegraph master, have invented an invention entitled An Improved Method of Applying Wave-Power on and these two motions are by appropriatemechanism added to each other, so as to produce a rota-tion of a shaft in one uniform direction, as hereinafter more fully set forth.

In this construction, R is the independent body, which is free to oscillate on a point of suspension. It is suspended by the rod a a on the secondary axis b b, (see Figs. 2 and 3, saine plate.) This axis is part of the frame m a', which itself is free to revolve on the primary axis c c at right angles to b b, and supported by bearings c e', Fig. 1, upon deck. The shaft cl d revolves through the hollow bearing or trunnion c at o, and also through a circular orifice in the center of the secondary axis b b,- the other end of d d revolves in a trunnion in the center of the wheel p. c and f are ratchet bevel-wheels revolving loosely on the axis b b, and geared to the bevel-wheel g, which is keyed to the shaft d d. The rival pawls are fitted at h upon the rod a a.. 7c is a ratchet-wheel keyed on the shaft d d. lis a pawl fixed on deck, working in the teeth of k, the teeth being set so that the pawl allows it to travel with the shaft d d. n is aratchet bevelwheel loose upon the shaft d d, the teeth beingl set opposite ways to those of 7.',- m, the pawl working in it from the deck. Midway between n and p the shaft d d carries a projecting arm, d o, upon which as an axis a loose epicyclic bevel-wheel, o, works, geared on the one side with the loose wheel fn, and on the other with a fixed bevel-wheel, p, which works the shaft q. r is merely a loose clutch, such as is usual to avert the effects of the straining of the ship on the machinery. s s, Fig. 2, is an arm or projection from the frame a', carrying a pawl, t, which also catches the teeth of 'the ratchet n.

The motion of a bodyround acenter in any direction or plane being referable to motion on two axes at right an gles to each other, the effect of the arrangement herein is the same as if the weight R were suspended by a Iilament from the exact center of intersection t' of the axes b b and c c, and the system or frame x is a universal or gyroscopic axis-the apparent inclination of the weight R from the vertical axis of the ship being resolved into angular motions on the two axes b b and c c. Now, the motion to and fro on the secondary axis b b causes motion of the wheel g and of the shaft d d in one direction relatively to the frame a: x; but if the frame a: no itself have motion on the axis c c, the whole motion of d d relatively to the deck will be the sum or difference of the motions, according as the frame oscillates against or with the continuous direction of g. But in the latter case the pawl Z catches the ratchet k, preventing d d from retrograding along with the frame, and the relative motion of the deck with the frame is made relative to the shaft d d, and reversed by means ofthe pawlt on the arms es, forcing the wheel o. round in a direction opposite to that in which d d can only revolve, and d d being immovable by virtue of the pawl l, the motion of n is Iransferred and reversed through the epicyclic wheel o to the wheel p, the result being that the simultaneous motions of R upon both axes, no matter how irregular, are added together, the shaft q being impelled with the sum of the motions, whence it is applied to the niechanical work required.

I claim as new and of my invention- The frame x x, primary axis c c supported in bearings v c, secondary axis b b, and oscillating weight R, in combination with the shafts d q, wheels g 7c 'a o p, and pawls m and t, the whole constructed and operated to give rotation of a shaft in one direction, as and for the purpose set forth.
